What is the function of a wrist pin bushing?

A wrist pin bushing, also known as a connecting rod bushing, sits between the piston pin (wrist pin) and the connecting rod. Its main job is to provide a smooth, durable surface for the piston pin to pivot within the connecting rod, allowing for the necessary movement as the piston travels up and down.

Why is proper clearance important for this part?

Maintaining the correct clearance is vital. Too much clearance can lead to excessive play, noise, and accelerated wear on both the bushing and the piston pin. Too little clearance can cause binding, increased friction, and potential damage to the connecting rod or piston.

Does this bushing come with a piston pin?

This product is for the wrist pin bushing only. The piston pin (wrist pin) is typically sold separately, and you will need to ensure you have the correct size pin for this bushing.
